Embodiment 1
[0039] According to the above recipe 1 # Calculate the weight percent of the glass from the molar composition in the glass, then weigh a total of 25Kg of raw materials, and mix them uniformly in the mixing box. Add the prepared powder into the 11-liter platinum crucible in turn, and heat and melt it through a silicon carbide electric furnace. The melting temperature is controlled at about 1280 ° C, and the melting time is 6 hours. The liquid is stirred. After the glass liquid has been clarified to remove air bubbles and fully stirred evenly, the high-temperature glass liquid is injected into the copper mold preheated to 300°C through the leak nozzle at the bottom of the crucible to form a glass blank, and the formed glass sample is quickly demolded and placed in the Has been heated to the annealing temperature (set at the transition temperature T of the glass g In the muffle furnace nearby), after 12 hours of heat preservation, the temperature is lowered to 100°C at a coolin...
